NEW YORK ( InvestorPlace) -- The best stocks for 2011 continue to be commodity stocks for many investors. Gold and silver prices have rolled back from highs at the end of 2010, but are still near record levels. Thanks to the prospect of commodity inflation due to a weak dollar and glimmers of an economic recovery, many experts are predicting gold prices to rally and silver to continue to set new highs in the months ahead. Along with these precious metals, some expect other materials like copper and steel to soar as well.

It's shaping up to be a big year for metal and mining stocks -- if you believe the hype. However, not all miners are in the clear even if you believe in this commodity inflation prediction. The fact is that some poorly run metal and mining stocks have lackluster fundamentals and should be sold immediately.

Here are six top miners that should be dropped from your stock portfolio.


Operating in Korea, Posco ( PKX) is an integrated steel producer. Over the past 12 months, PKX's stock performance has been anything but thrilling. Since last January, this stock is down 21%, compared to gains of 11% and 10% for the S&P 500 and Dow Jones Industrial Average, respectively. Another startling number is Posco's quarterly revenue growth which was down 15% year over year. Sell now.

Gerdau ( GGB)

Gerdau ( GGB) produces long-rolled steel in Brazil, and operates separate steel mills in the same country. Over the past 52 weeks, this mining stock has posted a loss of 19%, compared with gains in the broader markets. Shareholders are also not thrilled by GGB's earnings. Experts are predicting earnings of just 18 cents a share this quarter, compared with EPS of 53 cents, which GGB posted this time last year.

GGB may be one of the cheaper stocks on this list with a yearly range of $11.49 to $17.99, and should still be sold now before it loses any more value.

Aluminum Corp. of China

Aluminum producer Aluminum Corp. of China ( ACH) also has operations in bauxite mining, alumina refining, primary aluminum smelting and aluminum fabrication. Since last January, this mining stock has dropped 29%. Shareholders must also not be pleased by the company's net profit margin of just 1% that was posted in its last income statement. The stock doesn't seem to be rebounding at all either, and is down 7% over the past three months.


Global steel producer ArcelorMittal ( MT) operates in 20 countries and four continents. Impressively, the company owns 65 mini-mill and integrated mini-mill steelmaking facilities in those countries. Since this time last year, MT has slid 30%. Things have looked bleak in 2011 as well, and the stock is down 9% since the start of the new year. Last year, MT posted EPS of 68 cents during this quarter, but this year experts are projecting EPS of just 18 cents. MT has been giving shareholders headaches for the past year, and it's time you sell this stock if you haven't already.

Companhia Siderurgica Nacional

Integrated steel producer Companhia Siderurgica Nacional ( SID) operates in Brazil and Latin America. Its product line includes slabs, hot- and cold-rolled, galvanized and tin mill products. Since April this mining stock has dropped 13%. . Another startling statistic from SID's last income statement is the stock's net profit margin which was down 3%. In the last three months, SID stock has not performed well either, and is down 1% in that time. Sell SID now.

Kinross Gold

Rounding out the list of mining stocks to sell is Kinross Gold ( KGC). Kinross is involved throughout the mining process, and its activities include exploration and acquisition of gold-bearing properties, the extraction and processing of gold-containing ore, and reclamation of gold-mining properties. While KGC may appear to be a comprehensive mining company, its stock performance has been lackluster all year. Since last January, KGC has lost 15%. The stock is down 9% in the last three months.

Earnings are also down for KGC. Experts are predicting EPS of 16 cents this quarter after KGC posted EPS of 21 cents during the same quarter last year.
